Composting is reaching Antiquities agricultural practice mandated to produce valuable fertilizers. In the second half of the twentieth century was begun use this practice for the utilization of the organic fraction of municipal waste and sludge from sewage treatment plants and such application of this process dominates today. It does not mean, however, that ceased production of compost from "traditional" materials, they are not used as fertilizers in horticulture. The aim of the study was to estimate diversify of Cd, Pb, Zn and Cu contents in composts produced in different technologies and places but made of a similar feed material. The research material was obtained from the Krakow City (MPO Krakow) Composting Plant in Barycz, a Composting Plant at Plaszow (Krakow district) belonging to a private company Ekokonsorcjum-Effect and the three domestic composting piles located in the villages near Krakow: Bobin, Czarnochowice and Rzozow and from an allotments located at Krakow (Praska Street). Charge material for compost were taken: waste from the care of green areas of Krakow City, waste from Krakow marketplaces, which sold fruit and vegetables, weeds from weeding, the remains of cultivated plants (non-consumption parts), home waste food. The contents of the analysed ...
The activity of steel and chemical industries, fertilizers and the development of transport mean that heavy metals (copper) in toxic quantities directly affect the condition of soil and natural ecosystems occurring in nature. The study concerned aimed at the assess-ment of the copper content in the soil samples and plant material from the area of the mu-nicipality of Trzebinia where the problem of the presence of toxic heavy metals in soils is long-term and is the result of anthropogenic human impact on the environment. 83 research areas were designated from which the plant material and soil samples were taken from the levels of 0-20 cm and of 20-40 cm. The copper content in the soil was determined by apply-ing the FAA Method.Additionally, in the soil samples the following were marked: granulometric compo-sition, soil reaction in 1M KCl and in water, electrolytic conductivity and organic matter content. The content of the aforementioned element in the plant material was evaluated by applying the Atomic Absorption Spectrometry. The conducted research did not reveal any copper contamination of the soil in the municipality of Trzebinia (Journal of Laws 2002). The plant material did not exceed any IUNG standards of ...
